---

SYNTAXint XIntersectRegion ( Region sra , Region srb , Region dr_return ); int XUnionRegion ( Region sra , Region srb , Region dr_return ); int XUnionRectWithRegion ( XRectangle *rectangle , Region src_region , Region dest_region_return ); int XSubtractRegion ( Region sra , Region srb , Region dr_return ); int XXorRegion ( Region sra , Region srb , Region dr_return ); int XOffsetRegion ( Region r , int dx , int dy ); int XShrinkRegion ( Region r , int dx , int dy );

---

ARGUMENTSdest_region_return Returns the destination region. dr_return Returns the result of the computation. dx 
.ns dy Specify the x and y coordinates, which define the amount you want to move or shrink the specified region. r Specifies the region. rectangle Specifies the rectangle. sra 
.ns srb Specify the two regions with which you want to perform the computation. src_region Specifies the source region to be used.

---

DESCRIPTIONThe XIntersectRegion function computes the intersection of two regions. The XUnionRegion function computes the union of two regions. The XUnionRectWithRegion function updates the destination region from a union of the specified rectangle and the specified source region. The XSubtractRegion function subtracts srb from sra and stores the results in dr_return. The XXorRegion function calculates the difference between the union and intersection of two regions. The XOffsetRegion function moves the specified region by a specified amount. The XShrinkRegion function reduces the specified region by a specified amount. Positive values shrink the size of the region, and negative values expand the region.
